Abstract:
A long-term experiment was carried out in a mature orange grove comparing broadcasting versus continuous application of nitrogen at three rates (80, 160, 280 kg ha-1), 22 kg P ha-1 and 126 kg K ha-1 annually. The trees were irrigated with minispriklers wetting 70% of the soil area. The level of NO3-N in the leaves varied according to the rate of N application. Leaf K and P content were not affected by fertilization. High N applications caused excess N in the soil solution. The rate of N application did not affect orange yield, fruit size or quality. Fertigation at 160 kg N ha-1 caused higher yields than when the same amount of fertilizer was broadcast. At the high application rate, no differences between modes of application were found. © 1988 Kluwer Academic Publishers.
